OK, let me rephrase:
1. It takes an average of a number of years of consistent training to acquire the basic information and knowledge of one art.
2. Knowledge perspective is broadened by seeing and understanding the connections between similarities AND differences in patterned movement of other arts.
3. Wisdom comes thru understanding and experience in applied knowledge.

Since you've already addressed the issue of difference distinction, how then does ingrained habits in compartmentalized training serve to create understanding of another training modality?
